I just did a water change and noticed that my betta's poop is a red-ish colour instead of its normal black/green/brown. Are there any issues on this? Or is this normal? (the pellets that we give him are green/blue colouring) I've also been noticing that he has been having a curved spine (Downwards) is that normal??? (the water looks cloudy because of the glass being weird. ) PLEASE HELP!!!
